Réponses physiologiques des plantes aux polluants du sol

Abstract

Soil pollution has become in a few decades one of the major problems that conditions the future of our planet results from the consequences of various human activities (industrial, agricultural ...) accumulated over time. Our study consists in studying the physiological response of plants to the various pollutants of the soil among the principal pollutants selected for this work and more frequently met in the soils are: heavy metals, hydrocarbons and pesticides. The accumulation of different pollutants in the soil, water or air, constitutes a threat. The fact that they can move up the trophic chain represents a danger for ecosystems and for the health of living organisms and can have catastrophic social, environmental and economic consequences. Under stressful conditions, plants can react by implementing physiological and biochemical mechanisms, among others. In this context, our research work aims to evaluate the effect of pollutants on morphological, physiological and biochemical parameters of plants
